Description

本発明は、グロメット、及び、ワイヤハーネスに関する。 The present invention relates to grommets and wire harnesses.

車両に搭載される従来のグロメットとして、例えば、特許文献１には、ワイヤハーネスやウォッシャホース等の導出部材が挿通されるパネル部材に穿設された透孔に取付けられるグロメットが開示されている。このグロメットは、固定部と保持部とが一体に形成された弾性部材よりなり、折り返し部を備える。固定部は、パネル部材に穿設された透孔に固定する。保持部は、透孔を介して導出される導出部材が挿通される挿通孔を有して導出部材を保持する。折り返し部は、保持部の一端から導出部材の挿通方向に沿って筒状に延設され、挿通孔に導出部材が挿通された状態で保持部側へと折り返されることで保持部を導出部材に押圧する。 As a conventional grommet mounted on a vehicle, for example, Patent Document 1 discloses a grommet attached to a through hole formed in a panel member through which a lead-out member such as a wire harness or a washer hose is inserted. This grommet is made of an elastic member in which a fixing portion and a holding portion are integrally formed, and includes a folded portion. The fixing portion is fixed to a through hole formed in the panel member. The holding portion has an insertion hole through which the lead-out member led out through the through hole is inserted, and holds the lead-out member. The folded-back portion extends in a tubular shape from one end of the holding portion along the insertion direction of the lead-out member, and is folded back toward the holding portion with the lead-out member inserted through the insertion hole to make the holding portion into the lead-out member. Press.

ここで、グロメットは、パネル部材によって隔てられる一方の空間側から他方の空間側への止水の目的としても配置されるが、止水を効果的に行うためには、導出部材を覆う部分を長くする必要がある。しかし、導出部材を覆う部分を長くした場合、グロメットに導出部材を通すのが困難になり、ワイヤハーネスやウォッシャホース等の導出部材の組み付け時の作業性が低下する虞があった。 Here, the grommet is also arranged for the purpose of stopping water from one space side to the other space side separated by the panel member, but in order to effectively stop water, a portion covering the lead-out member is provided. It needs to be long. However, when the portion covering the lead-out member is lengthened, it becomes difficult to pass the lead-out member through the grommet, and there is a risk that workability at the time of assembling the lead-out member such as a wire harness or a washer hose is lowered.

本発明は、上記に鑑みてなされたものであって、グロメットの組み付け作業時の作業性の低下を抑制しつつ、止水性能を向上させることのできるグロメット、及び、ワイヤハーネスを提供することを目的とする。 The present invention has been made in view of the above, and provides a grommet and a wire harness capable of improving water stopping performance while suppressing a decrease in workability during assembling work of the grommet. The purpose.

上述した課題を解決し、目的を達成するために、本発明に係るグロメットは、取付対象を軸線方向に沿って貫通する貫通孔に嵌合し当該貫通孔を止水すると共に内部に前記軸線方向に沿って配索材が挿通される本体部と、前記本体部と一体で筒状に形成され内部に前記軸線方向に沿って前記配索材が挿通される筒状部とを備え、前記筒状部は、前記本体部から連続して形成される筒状部本体と、前記軸線方向における前記本体部が位置する側の反対側で前記筒状部本体から連続して形成される折り返し部とを有し、前記折り返し部は、前記折り返し部が前記筒状部本体の外側に折り返された装着位置と、前記折り返し部が前記筒状部本体に対して前記本体部が位置する側の反対側に位置する使用位置とに折り返し可能であることを特徴とする。 In order to solve the above-mentioned problems and achieve the object, the grommet according to the present invention fits the mounting object into a through hole penetrating along the axial direction, stops the water through the through hole, and internally has the axial direction. A main body portion through which the cording material is inserted along the line and a tubular portion integrally formed with the main body portion and through which the cording material is inserted along the axial direction are provided inside the cylinder. The shaped portion includes a tubular portion main body that is continuously formed from the main body portion and a folded portion that is continuously formed from the tubular portion main body on the opposite side of the axial direction from the side where the main body portion is located. The folded portion has a mounting position in which the folded portion is folded back to the outside of the tubular portion main body, and the folded portion is on the opposite side of the tubular portion main body from which the main body portion is located. It is characterized in that it can be folded back to the used position located in.

また、上記グロメットでは、前記折り返し部は、前記使用位置において、内面の周方向における全長が、前記筒状部本体の内面の周方向における全長よりも長く、前記筒状部本体側に折り返された状態では、径方向への収縮力を発生させることなく前記筒状部本体の径方向における外側に配置される。 Further, in the grommet, at the used position, the total length of the inner surface in the circumferential direction is longer than the total length of the inner surface of the tubular portion main body in the circumferential direction, and the folded portion is folded back toward the tubular portion main body. In the state, it is arranged on the outer side in the radial direction of the tubular portion main body without generating a contraction force in the radial direction.

また、上記グロメットでは、前記折り返し部は、前記使用位置において、内面の直径が前記筒状部本体の内面の直径より大きく、前記筒状部本体との間に段差部を有する。 Further, in the grommet, the diameter of the inner surface of the folded portion is larger than the diameter of the inner surface of the tubular portion main body at the used position, and the folded portion has a stepped portion with the tubular portion main body.

また、上記グロメットでは、前記折り返し部は、前記装着位置において周方向に開き、前記使用位置において周方向に折り畳まれる折り畳み部を有する。 Further, in the grommet, the folded portion has a folded portion that opens in the circumferential direction at the mounting position and is folded in the circumferential direction at the used position.

上記目的を達成するために、本発明に係るワイヤハーネスは、導電性を有する配索材と、前記配索材に設けられるグロメットとを備え、前記グロメットは、取付対象を軸線方向に沿って貫通する貫通孔に嵌合し当該貫通孔を止水すると共に内部に前記軸線方向に沿って前記配索材が挿通される本体部と、前記本体部と一体で筒状に形成され内部に前記軸線方向に沿って前記配索材が挿通される筒状部とを備え、前記筒状部は、前記本体部から連続して形成される筒状部本体と、前記軸線方向における前記本体部が位置する側の反対側で前記筒状部本体から連続して形成される折り返し部とを有し、前記折り返し部は、前記折り返し部が前記筒状部本体の外側に折り返された装着位置と、前記折り返し部が前記筒状部本体に対して前記本体部が位置する側の反対側に位置する使用位置とに折り返し可能であることを特徴とする。 In order to achieve the above object, the wire harness according to the present invention includes a conductive wiring material and a grommet provided on the wiring material, and the grommet penetrates the attachment target along the axial direction. A main body portion that fits into the through hole to be fitted and water is stopped, and the wiring material is inserted along the axis direction inside, and the main body portion is integrally formed into a tubular shape and the axis line is internally formed. A tubular portion through which the wiring material is inserted is provided along the direction, and the tubular portion includes a tubular portion main body formed continuously from the main body portion and a position of the main body portion in the axial direction. The folded portion has a folded portion formed continuously from the tubular portion main body on the opposite side to the side to be formed, and the folded portion includes a mounting position in which the folded portion is folded to the outside of the tubular portion main body and the above. It is characterized in that the folded-back portion can be folded back to a used position located on the opposite side of the tubular portion main body from the side on which the main body portion is located.

本発明に係るグロメット、及び、ワイヤハーネスは、本体部と筒状部とを備えると共に、筒状部は筒状部本体と折り返し部とを有し、折り返し部は、折り返し部が筒状部本体の外側に折り返された装着位置と、折り返し部が筒状部本体に対して本体部が位置する側の反対側に位置する使用位置とに折り返し可能になっている。このため、グロメットやワイヤハーネスの使用時には、筒状部は、折り返し部を使用位置にすることにより軸線方向における長さが長い状態で配索材を覆うことができるため、止水性能を高めることができる。また、配索材にグロメットを装着する際には、折り返し部を折り返した装着位置の状態にして軸線方向における筒状部の長さが短い状態で装着することにより、容易に装着することができる。この結果、グロメットの組み付け作業時の作業性の低下を抑制しつつ、被水対策の効果を向上させることのできる、という効果を奏する。 The grommet and the wire harness according to the present invention include a main body portion and a tubular portion, the tubular portion has a tubular portion main body and a folded portion, and the folded portion has a tubular portion main body. It is possible to fold back to the mounting position that is folded back to the outside and the usage position where the folded part is located on the opposite side of the tubular part body where the main body is located. For this reason, when using a grommet or a wire harness, the tubular portion can cover the wiring material in a state where the length in the axial direction is long by setting the folded portion at the use position, so that the water stopping performance is improved. Can be done. Further, when the grommet is attached to the wiring material, it can be easily attached by setting the folded portion in the folded attachment position and attaching the grommet in a state where the length of the tubular portion in the axial direction is short. .. As a result, it is possible to improve the effect of water exposure countermeasures while suppressing a decrease in workability during the assembly work of the grommet.

以下に、本発明に係る実施形態を図面に基づいて詳細に説明する。なお、この実施形態によりこの発明が限定されるものではない。また、下記実施形態における構成要素には、当業者が置換可能かつ容易なもの、あるいは実質的に同一のものが含まれる。 Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. The present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that can be easily replaced by those skilled in the art, or those that are substantially the same.

［実施形態１］
図１、図２、図３に示す本実施形態１のグロメット１は、車両等に配索されるワイヤハーネスＷＨに組み込まれるものである。ここで、ワイヤハーネスＷＨは、例えば、車両に搭載される各機器間の接続のために、電源供給や信号通信に用いられる複数の配索材Ｗを束にして集合部品とし、コネクタ等で複数の配索材Ｗを各機器に接続するようにしたものである。ワイヤハーネスＷＨは、導電性を有する配索材Ｗと、配索材Ｗに設けられ当該配索材Ｗが挿通されるグロメット１とを備える。ワイヤハーネスＷＨは、この他、さらに、コルゲートチューブ、樹脂テープ、プロテクタ等の外装部材、電気接続箱、固定具など種々の構成部品を含んで構成されてもよい。配索材Ｗは、例えば、金属棒、電線、電線束等によって構成される。金属棒は、導電性を有する棒状部材の外側を、絶縁性を有する被覆部によって覆ったものである。電線は、複数の導電性を有する金属素線からなる導体部（芯線）の外側を、絶縁性を有する被覆部によって覆ったものである。電線束は、当該電線を束ねたものである。ワイヤハーネスＷＨは、複数の配索材Ｗを束ねて集約すると共に、束ねられた配索材Ｗの端末に設けられたコネクタ等を介して各種機器が電気的に接続される。 [Embodiment 1]
The grommet 1 of the first embodiment shown in FIGS. 1, 2 and 3 is incorporated in a wire harness WH distributed to a vehicle or the like. Here, the wire harness WH is, for example, a bundle of a plurality of wiring materials W used for power supply and signal communication for connection between devices mounted on a vehicle, and a plurality of wire harnesses WH such as connectors. The wiring material W is connected to each device. The wire harness WH includes a conductive wiring material W and a grommet 1 provided in the wiring material W through which the wiring material W is inserted. The wire harness WH may further include various components such as corrugated tubes, resin tapes, exterior members such as protectors, electrical junction boxes, and fixtures. The wiring material W is composed of, for example, a metal rod, an electric wire, a bundle of electric wires, and the like. The metal rod is formed by covering the outside of a rod-shaped member having conductivity with an insulating coating portion. An electric wire is formed by covering the outside of a conductor portion (core wire) made of a plurality of conductive metal strands with an insulating covering portion. The electric wire bundle is a bundle of the electric wires. In the wire harness WH, a plurality of wiring materials W are bundled and aggregated, and various devices are electrically connected via a connector or the like provided at the terminal of the bundled wiring materials W.

そして、グロメット１は、取付対象である取付パネル１００に形成された貫通孔１０１を介して当該取付パネル１００を境界にして区画される２つの空間に渡って配索材Ｗを配索する際に当該貫通孔１０１に適用されるものである。取付パネル１００は、例えば、車両のボデー等を構成する金属板であり、貫通孔１０１は、当該取付パネル１００を板厚方向に沿って貫通する。取付パネル１００を境界にして区画される２つの空間とは、典型的には、車内空間（例えば、キャビン）と車外空間（例えば、エンジンコンパートメント）である。そして、グロメット１は、当該ワイヤハーネスＷＨの配索材Ｗが挿通され当該配索材Ｗの周囲に外装された状態で貫通孔１０１に組み付けられることで、貫通孔１０１を通る配索材Ｗを保護すると共に当該貫通孔１０１を止水（防水）するものである。グロメット１は、貫通孔１０１の防水の他、防塵、遮音等の機能も有する。以下、各図を参照してグロメット１の構成について詳細に説明する。 Then, when the grommet 1 distributes the wiring material W over the two spaces partitioned by the mounting panel 100 as a boundary through the through hole 101 formed in the mounting panel 100 to be mounted. It is applied to the through hole 101. The mounting panel 100 is, for example, a metal plate constituting a body of a vehicle or the like, and the through hole 101 penetrates the mounting panel 100 along the plate thickness direction. The two spaces partitioned by the mounting panel 100 are typically an interior space (eg, cabin) and an exterior space (eg, engine compartment). Then, the grommet 1 is assembled into the through hole 101 in a state where the wire harness W of the wire harness WH is inserted and is externally attached to the periphery of the wire harness W, so that the grommet 1 passes through the through hole 101. It protects and stops (waterproofs) the through hole 101. The grommet 1 has functions such as dustproof and sound insulation as well as waterproofing of the through hole 101. Hereinafter, the configuration of the grommet 1 will be described in detail with reference to each figure.

なお、図１、図２、図３は、取付パネル１００を二点鎖線で省略して図示し、他図は、取付パネル１００の図示自体を省略している。また、各図は、配索材Ｗ、取付パネル１００を二点鎖線で省略して図示している。また、以下の説明では、互いに交差する第１方向、第２方向、及び、第３方向のうち、第１方向を「軸線方向Ｘ」といい、第２方向を「幅方向Ｙ」といい、第３方向を「高さ方向Ｚ」という。軸線方向Ｘと幅方向Ｙと高さ方向Ｚとは、典型的には、相互に直交する。ここでは、軸線方向Ｘは、上述した取付パネル１００の板厚方向に相当し、貫通孔１０１に対する配索材Ｗ、グロメット１の挿通方向に相当する。言い換えれば、軸線方向Ｘは、グロメット１に挿通された配索材Ｗの延在方向に沿う方向であり、取付パネル１００の貫通孔１０１は、取付パネル１００を軸線方向Ｘに沿って貫通する。幅方向Ｙ、高さ方向Ｚは、取付パネル１００の延在方向に相当する。ここでは、説明をわかり易くするため便宜的に、配索材Ｗが軸線方向Ｘに沿って直線状に配索されるものとして説明するがこれに限らず、グロメット１が取付パネル１００に取り付けられた状態で、軸線方向Ｘが屈曲した方向とされ、当該グロメット１、及び、配索材Ｗが一部で屈曲されて設けられるものであってもよい。また、以下の説明で用いる各方向は、特に断りのない限り、グロメット１が取付パネル１００に組み付けられた状態での方向として説明する。 Note that, in FIGS. 1, 2, and 3, the mounting panel 100 is omitted by a two-dot chain line, and in the other drawings, the mounting panel 100 is not shown. Further, in each figure, the wiring material W and the mounting panel 100 are omitted by a two-dot chain line. Further, in the following description, of the first direction, the second direction, and the third direction that intersect each other, the first direction is referred to as "axis direction X" and the second direction is referred to as "width direction Y". The third direction is called "height direction Z". The axial direction X, the width direction Y, and the height direction Z are typically orthogonal to each other. Here, the axial direction X corresponds to the plate thickness direction of the mounting panel 100 described above, and corresponds to the insertion direction of the wiring material W and the grommet 1 with respect to the through hole 101. In other words, the axial direction X is the direction along the extending direction of the wiring material W inserted through the grommet 1, and the through hole 101 of the mounting panel 100 penetrates the mounting panel 100 along the axial direction X. The width direction Y and the height direction Z correspond to the extending directions of the mounting panel 100. Here, for the sake of convenience, the wiring material W will be described as being linearly arranged along the axial direction X, but the present invention is not limited to this, and the grommet 1 is attached to the attachment panel 100. In this state, the axial direction X may be a bent direction, and the grommet 1 and the wiring material W may be partially bent and provided. Further, each direction used in the following description will be described as a direction in which the grommet 1 is assembled to the mounting panel 100 unless otherwise specified.

具体的には、本実施形態１のグロメット１は、図１、図２、図３に示すように、内部に配索材Ｗが軸線方向Ｘに沿って挿通され、取付パネル１００の貫通孔１０１との間を止水可能なシール部材である。グロメット１は、本体部１０、筒状部２０、及び、筒状部３０を含んで構成され、これらが一体となって弾性体として形成される。グロメット１は、例えば、ゴムや熱可塑性エラストマー等、剛性が低く高い可撓性を有する絶縁性の弾性樹脂材料（例えば、エチレン−プロピレン−ジエンゴム（ＥＰＤＭ）等）により形成される。 Specifically, in the grommet 1 of the present embodiment 1, as shown in FIGS. 1, 2, and 3, the wiring material W is inserted inside along the axial direction X, and the through hole 101 of the mounting panel 100 is inserted. It is a sealing member that can stop water between and. The grommet 1 is configured to include a main body portion 10, a tubular portion 20, and a tubular portion 30, and these are integrally formed as an elastic body. The grommet 1 is formed of an insulating elastic resin material having low rigidity and high flexibility (for example, ethylene-propylene-diene rubber (EPDM)) such as rubber or thermoplastic elastomer.

本体部１０は、貫通孔１０１に嵌合し当該貫通孔１０１を止水すると共に内部に軸線方向Ｘに沿って配索材Ｗが挿通される部分である。本体部１０は、第１膨出部１１、第２膨出部１２、嵌合溝部１３、及び、リップ部１４を含んで構成される。 The main body portion 10 is a portion that fits into the through hole 101, stops water from the through hole 101, and inserts a wiring material W inside along the axial direction X. The main body portion 10 includes a first bulging portion 11, a second bulging portion 12, a fitting groove portion 13, and a lip portion 14.

第１膨出部１１、第２膨出部１２は、それぞれ中心軸線Ｃが軸線方向Ｘに沿った環状、ここでは筒状に形成される。第１膨出部１１と第２膨出部１２とは、軸線方向Ｘに沿って空間をあけて対向し外周部１０Ａで一体化されている。ここで、外周部１０Ａとは、第１膨出部１１、第２膨出部１２とのそれぞれの径方向（中心軸線Ｃと直交する方向）の外側の端部付近の位置で、双方に接続される部分である。 The central axis C of each of the first bulging portion 11 and the second bulging portion 12 is formed in an annular shape along the axial direction X, in this case, in a tubular shape. The first bulging portion 11 and the second bulging portion 12 face each other with a space along the axial direction X, and are integrated by the outer peripheral portion 10A. Here, the outer peripheral portion 10A is connected to both of the first bulging portion 11 and the second bulging portion 12 at positions near the outer end portions in the radial direction (direction orthogonal to the central axis C). It is the part to be done.

The first bulging portion 11 and the second bulging portion 12 are formed in a hollow dome shape as a whole in a state of being integrated by the outer peripheral portion 10A.

The fitting groove portion 13 is formed on the outer peripheral portion 10A as an annular groove portion centered on the central axis C. In the fitting groove portion 13, the edge portion forming the through hole 101 in the mounting panel 100 is fitted in the state where the main body portion 10 is fitted in the through hole 101.

リップ部１４は、嵌合溝部１３に沿って形成される襞状の止水部である。ここでは、リップ部１４は、嵌合溝部１３における第１膨出部１１側の端部に嵌合溝部１３に沿って円環状に形成される。つまり、リップ部１４は、嵌合溝部１３に、中心軸線Ｃを中心とした円環状に形成される。リップ部１４は、貫通孔１０１の縁部が嵌合溝部１３に嵌合した状態で当該縁部の表面（ここでは、第１膨出部１１側の面）に接触し当該表面との間を止水する。リップ部１４は、弾性変形によって当該貫通孔１０１を形成する縁部の表面に密着し、貫通孔１０１の全周縁をシールするよう構成される。 The lip portion 14 is a fold-shaped water blocking portion formed along the fitting groove portion 13. Here, the lip portion 14 is formed in an annular shape along the fitting groove portion 13 at the end portion of the fitting groove portion 13 on the first bulging portion 11 side. That is, the lip portion 14 is formed in the fitting groove portion 13 in an annular shape centered on the central axis C. The lip portion 14 comes into contact with the surface of the edge portion (here, the surface on the first bulging portion 11 side) in a state where the edge portion of the through hole 101 is fitted into the fitting groove portion 13, and is in contact with the surface. Stop the water. The lip portion 14 is configured to adhere to the surface of the edge portion forming the through hole 101 by elastic deformation and seal the entire peripheral edge of the through hole 101.

筒状部２０、３０は、本体部１０と一体で筒状に形成され内部に軸線方向Ｘに沿って配索材Ｗが挿通される部分である。 The tubular portions 20 and 30 are portions that are formed in a tubular shape integrally with the main body portion 10 and into which the wiring material W is inserted along the axial direction X.

筒状部２０は、第１膨出部１１から軸線方向Ｘに沿って一方側（第２膨出部１２とは反対側）に突出するように形成される。筒状部２０は、中心軸線Ｃを中心とした円筒状に形成され、軸線方向Ｘに沿って延在する。筒状部２０は、第１膨出部１１の大部分より小径の円筒状に形成される。筒状部２０は、軸線方向Ｘの一方側の端部が開口し、他方側の端部が第１膨出部１１に接続される。筒状部２０は、幅方向Ｙ、及び、高さ方向Ｚに対して、第１膨出部１１の略中央位置に接続される。筒状部２０は、蛇腹部２１を有している。蛇腹部２１は、軸線方向Ｘにおける筒状部２０の一部が蛇腹状に形成されることによって形成されている。即ち、蛇腹部２１は、軸線方向Ｘにおける筒状部２０の一部が、軸線方向Ｘの一方向に向かうに従って、直径が大きくなる方向への変化と小さくなる方向への変化とが交互に入れ変わる形状で形成されている。筒状部２０は、蛇腹部２１を有することにより、蛇腹部２１の位置で容易に湾曲することが可能になっている。なお、この筒状部２０の構成については、後で詳細に説明する。 The tubular portion 20 is formed so as to project from the first bulging portion 11 to one side (the side opposite to the second bulging portion 12) along the axial direction X. The tubular portion 20 is formed in a cylindrical shape centered on the central axis C, and extends along the axis direction X. The tubular portion 20 is formed in a cylindrical shape having a smaller diameter than most of the first bulging portion 11. In the tubular portion 20, one end of the axial direction X is opened, and the other end is connected to the first bulging portion 11. The tubular portion 20 is connected to a substantially central position of the first bulging portion 11 with respect to the width direction Y and the height direction Z. The tubular portion 20 has a bellows portion 21. The bellows portion 21 is formed by forming a part of the tubular portion 20 in the axial direction X in a bellows shape. That is, in the bellows portion 21, a part of the tubular portion 20 in the axial direction X alternately inserts a change in a direction in which the diameter increases and a change in a direction in which the diameter decreases in the direction of one direction of the axial direction X. It is formed in a changing shape. By having the bellows portion 21, the tubular portion 20 can be easily curved at the position of the bellows portion 21. The configuration of the tubular portion 20 will be described in detail later.

筒状部３０は、第２膨出部１２から軸線方向Ｘに沿って一方側（第１膨出部１１とは反対側）に突出するように形成される。筒状部３０は、中心軸線Ｃを中心とした円筒状に形成され、軸線方向Ｘに沿って延在する。筒状部３０は、第２膨出部１２の大部分より小径の円筒状に形成される。筒状部３０は、軸線方向Ｘの一方側の端部が開口し、他方側の端部が第２膨出部１２に接続される。筒状部３０は、幅方向Ｙ、及び、高さ方向Ｚに対して、第２膨出部１２の略中央位置に接続される。 The tubular portion 30 is formed so as to project from the second bulging portion 12 to one side (the side opposite to the first bulging portion 11) along the axial direction X. The tubular portion 30 is formed in a cylindrical shape centered on the central axis C, and extends along the axis direction X. The tubular portion 30 is formed in a cylindrical shape having a smaller diameter than most of the second bulging portion 12. In the tubular portion 30, one end of the axial direction X is opened, and the other end is connected to the second bulging portion 12. The tubular portion 30 is connected to a substantially central position of the second bulging portion 12 with respect to the width direction Y and the height direction Z.

上記のように構成されるグロメット１は、本体部１０、筒状部２０、及び、筒状部３０の内部空間部が挿通空間部４０として機能する。挿通空間部４０は、配索材Ｗが挿通される空間部であり、軸線方向Ｘに沿って筒状部２０、本体部１０、及び、筒状部３０に渡って連続する。グロメット１は、筒状部２０、本体部１０、及び、筒状部３０に渡って連通して形成される挿通空間部４０に対して配索材Ｗが軸線方向Ｘに沿って挿通される。 In the grommet 1 configured as described above, the main body portion 10, the tubular portion 20, and the internal space portion of the tubular portion 30 function as the insertion space portion 40. The insertion space portion 40 is a space portion through which the wiring material W is inserted, and is continuous along the axial direction X along the tubular portion 20, the main body portion 10, and the tubular portion 30. In the grommet 1, the wiring material W is inserted along the axial direction X into the insertion space portion 40 formed by communicating with the tubular portion 20, the main body portion 10, and the tubular portion 30.

グロメット１は、挿通空間部４０に配索材Ｗを挿通するようにして当該配索材Ｗに装着された後、配索材Ｗの末端と共に筒状部２０、又は筒状部３０が貫通孔１０１に挿通される。そして、グロメット１は、本体部１０の嵌合溝部１３に貫通孔１０１の縁部を嵌合させるようにして本体部１０が貫通孔１０１に嵌合されることで、取付パネル１００に組み付けられる。グロメット１は、この状態で、リップ部１４が弾性変形しつつ貫通孔１０１の周縁の表面に密着し、貫通孔１０１の全周縁をシールする。なお、グロメット１は、挿通空間部４０に挿通された配索材Ｗと筒状部２０、３０と配索材Ｗとに渡って巻きテープ等が巻き回されることで筒状部２０、３０の開口を止水するようにしてもよい。 After the grommet 1 is attached to the wiring material W so as to insert the wiring material W into the insertion space 40, the tubular portion 20 or the tubular portion 30 is formed through a through hole together with the end of the wiring material W. It is inserted through 101. Then, the grommet 1 is assembled to the mounting panel 100 by fitting the edge portion of the through hole 101 into the fitting groove portion 13 of the main body portion 10 and fitting the main body portion 10 into the through hole 101. In this state, the grommet 1 is in close contact with the surface of the peripheral edge of the through hole 101 while the lip portion 14 is elastically deformed, and seals the entire peripheral edge of the through hole 101. In the grommet 1, the tubular portions 20, 30 are formed by winding a winding tape or the like around the wiring material W, the tubular portions 20, 30 and the wiring material W inserted through the insertion space portion 40. The opening of the water may be stopped.

ここで、筒状部２０について詳しく説明する。筒状部２０は、筒状部本体５０と、折り返し部６０とを有している。筒状部本体５０は、筒状部２０において、本体部１０に接続されて本体部１０から連続して形成される部位になっており、蛇腹部２１は、筒状部本体５０に形成されている。 Here, the tubular portion 20 will be described in detail. The tubular portion 20 has a tubular portion main body 50 and a folded portion 60. The tubular portion main body 50 is a portion of the tubular portion 20 that is connected to the main body portion 10 and is continuously formed from the main body portion 10, and the bellows portion 21 is formed on the tubular portion main body 50. There is.

折り返し部６０は、軸線方向Ｘにおける本体部１０が位置する側の反対側で筒状部本体５０から連続して形成されると共に、後述する図４、図５に示すように、筒状部本体５０の径方向における外側に折り返し可能になっている。折り返し部６０が、筒状部本体５０の外側に折り返された状態の位置は、グロメット１を配索材Ｗに装着する際における位置である装着位置になっている。一方、図１、図２、図３に示すように、折り返し部６０が、筒状部本体５０に対して本体部１０が位置する側の反対側に位置する状態の位置は、配索材Ｗにグロメット１を装着したワイヤハーネスＷＨの使用時における位置である使用位置になっている。折り返し部６０は、この装着位置と使用位置とに折り返し可能になっている。本実施形態１のグロメット１は、典型的には、各部が装着位置にある位置関係で一体成型され、装着位置と使用位置とに折り返し可能とされる。 The folded-back portion 60 is formed continuously from the tubular portion main body 50 on the side opposite to the side where the main body portion 10 is located in the axial direction X, and as shown in FIGS. 4 and 5 described later, the tubular portion main body. It can be folded outward in the radial direction of 50. The position where the folded portion 60 is folded back to the outside of the tubular portion main body 50 is the mounting position which is the position when the grommet 1 is mounted on the wiring material W. On the other hand, as shown in FIGS. 1, 2 and 3, the position where the folded-back portion 60 is located on the opposite side of the tubular portion main body 50 from the side where the main body portion 10 is located is the wiring material W. This is the position in which the wire harness WH with the grommet 1 attached is used. The folded-back portion 60 can be folded back between the mounting position and the used position. The grommet 1 of the first embodiment is typically integrally molded in a positional relationship in which each part is in a mounting position, and can be folded back into a mounting position and a usage position.

折り返し部６０は、使用位置において、中心軸線Ｃを中心とする直径が、中心軸線Ｃを中心とする筒状部本体５０の直径よりも大きくなっている。これにより、折り返し部６０は、筒状部本体５０との間に段差部６２を有している。 The diameter of the folded-back portion 60 centered on the central axis C is larger than the diameter of the tubular portion main body 50 centered on the central axis C at the position of use. As a result, the folded-back portion 60 has a stepped portion 62 between the folded-back portion 60 and the tubular portion main body 50.

つまり、筒状部２０は、軸線方向Ｘにおいて段差部６２を境として直径が異なっており、段差部６２を境として、本体部１０が位置する側の反対側に位置する部分は、本体部１０が位置する側に位置する部分よりも直径が大きくなっている。このように、段差部６２を境として直径が異なる筒状部２０は、段差部６２よりも本体部１０が位置する側の反対側に位置する部分が折り返し部６０になっており、段差部６２よりも本体部１０が位置する側に位置する部分が筒状部本体５０になっている。 That is, the tubular portions 20 have different diameters in the axial direction X with the step portion 62 as a boundary, and the portion located on the opposite side of the step portion 62 from the side on which the main body portion 10 is located is the main body portion 10. The diameter is larger than the part located on the side where is located. As described above, in the tubular portion 20 having different diameters with the step portion 62 as a boundary, the portion located on the opposite side of the step portion 62 on the side where the main body portion 10 is located is the folded portion 60, and the step portion 62 The portion located on the side where the main body portion 10 is located is the tubular portion main body 50.

また、折り返し部６０は、中心軸線Ｃを中心とする直径が、中心軸線Ｃを中心とする筒状部本体５０の直径よりも大きくなっているため、折り返し部６０は、内面６１の直径も、筒状部本体５０の内面５１の直径より大きくなっている。このため、折り返し部６０は、使用位置において、内面６１の周方向における全長、即ち、中心軸線Ｃを中心とする周方向における内面６１の全長が、筒状部本体５０の内面５１の周方向における全長よりも長くなっている。また、折り返し部６０は、軸線方向Ｘにおける長さが、筒状部本体５０における、段差部６２から蛇腹部２１の位置までの長さと同程度の長さか、或いは、筒状部本体５０における段差部６２から蛇腹部２１の位置までの長さよりも短くなっている。 Further, since the diameter of the folded-back portion 60 centered on the central axis C is larger than the diameter of the tubular portion main body 50 centered on the central axis C, the folded-back portion 60 also has the diameter of the inner surface 61. It is larger than the diameter of the inner surface 51 of the tubular portion main body 50. Therefore, at the position of use, the total length of the folded-back portion 60 in the circumferential direction of the inner surface 61, that is, the total length of the inner surface 61 in the circumferential direction centered on the central axis C is in the circumferential direction of the inner surface 51 of the tubular portion main body 50. It is longer than the total length. Further, the length of the folded-back portion 60 in the axial direction X is about the same as the length from the step portion 62 to the position of the bellows portion 21 in the tubular portion main body 50, or the step in the tubular portion main body 50. It is shorter than the length from the portion 62 to the position of the bellows portion 21.

さらに、折り返し部６０には、切欠き部６３が形成されている。切欠き部６３は、筒状部２０において本体部１０に接続されている側の反対側に位置する開口端部２５から、中心軸線Ｃを中心とする周方向における幅が所定の幅で、軸線方向Ｘに沿って切り欠かれた部分になっている。切欠き部６３は、折り返し部６０に対して、中心軸線Ｃを中心とする点対称となる２箇所に形成されている。また、折り返し部６０の内面６１における開口端部２５の近傍には、内面６１から突出して中心軸線Ｃを中心とする周方向に延在するリブ６４が形成されている。リブ６４は、筒状部２０の内部に配索材Ｗが挿通され巻きテープ等が巻き回された状態で、弾性変形して配索材Ｗの外表面に密着し、当該配索材Ｗの全周をシールするリップ部として機能する。 Further, the folded-back portion 60 is formed with a notch portion 63. The notch 63 has an axis having a predetermined width in the circumferential direction centered on the central axis C from the opening end 25 located on the opposite side of the tubular portion 20 from the side connected to the main body 10. It is a notched part along the direction X. The notch 63 is formed at two points symmetrical with respect to the folded portion 60 about the central axis C. Further, in the vicinity of the opening end portion 25 on the inner surface 61 of the folded-back portion 60, a rib 64 that protrudes from the inner surface 61 and extends in the circumferential direction about the central axis C is formed. The rib 64 is elastically deformed in a state where the wiring material W is inserted into the tubular portion 20 and the winding tape or the like is wound around the rib 64, and the rib 64 adheres to the outer surface of the wiring material W. It functions as a lip part that seals the entire circumference.

なお、上述した折り返し部６０は内面６１の周方向における全長は、折り返し部６０に切欠き部６３が形成されていないと仮定した際における全長であり、切欠き部６３の位置にも折り返し部６０を形成する部材が配置されていると仮定した際における全長になっている。また、上述した折り返し部６０は内面６１の周方向における全長は、リブ６４以外の部分の全長になっている。 The total length of the folded-back portion 60 in the circumferential direction of the inner surface 61 is the total length when it is assumed that the cut-out portion 63 is not formed in the folded-back portion 60, and the folded-back portion 60 is also located at the position of the cutout portion 63. It is the total length when it is assumed that the members forming the above are arranged. Further, the total length of the folded-back portion 60 described above in the circumferential direction of the inner surface 61 is the total length of the portion other than the rib 64.

これらのように構成されるグロメット１に配索材Ｗを挿通する際には、折り返し部６０を折り返した状態で挿通する。図４は、図１に示すグロメット１の折り返し部６０を折り返した状態の斜視図である。図５は、図４に示すグロメット１の断面図である。折り返し部６０を折り返す際には、段差部６２の位置から、筒状部本体５０が位置する側に向けて折り返す。詳しくは、折り返し部６０は、開口端部２５を段差部６２よりも本体部１０寄りに位置させ、中心軸線Ｃを中心とする径方向における筒状部本体５０の外側から、筒状部本体５０を覆うように折り返す。これにより、折り返し部６０は、内面６１が外表面になる状態で、中心軸線Ｃを中心とする径方向における筒状部本体５０の外側に折り返される。また、折り返し部６０は、軸線方向Ｘにおける長さが、筒状部本体５０における段差部６２から蛇腹部２１の位置までの長さと同程度の長さになっているため、折り返し部６０は、概ね、筒状部本体５０における段差部６２から蛇腹部２１の位置までの範囲を外側から覆う状態になる。グロメット１は、筒状部本体５０が位置する側に折り返し部６０を折り返すことにより、折り返し部６０が折り返されていない状態と比較して、軸線方向Ｘにおける長さが短くなる。 When the wiring material W is inserted through the grommet 1 configured as described above, the folded-back portion 60 is inserted in a folded state. FIG. 4 is a perspective view of the folded portion 60 of the grommet 1 shown in FIG. 1 in a folded state. FIG. 5 is a cross-sectional view of the grommet 1 shown in FIG. When folding back the folded-back portion 60, the folded-back portion 60 is folded back from the position of the step portion 62 toward the side where the tubular portion main body 50 is located. Specifically, the folded-back portion 60 has the opening end portion 25 positioned closer to the main body portion 10 than the step portion 62, and the tubular portion main body 50 is viewed from the outside of the tubular portion main body 50 in the radial direction centered on the central axis C. Fold it back to cover it. As a result, the folded-back portion 60 is folded back to the outside of the tubular portion main body 50 in the radial direction centered on the central axis C with the inner surface 61 being the outer surface. Further, since the length of the folded-back portion 60 in the axial direction X is about the same as the length from the step portion 62 to the position of the bellows portion 21 in the tubular portion main body 50, the folded-back portion 60 is formed. Generally, the range from the step portion 62 to the position of the bellows portion 21 in the tubular portion main body 50 is covered from the outside. By folding the folded portion 60 toward the side where the tubular portion main body 50 is located, the grommet 1 has a shorter length in the axial direction X as compared with a state in which the folded portion 60 is not folded.

その際に、折り返し部６０は、内面６１の周方向における全長が、筒状部本体５０の内面５１の周方向における全長よりも長くなっているため、筒状部本体５０側に折り返された装着位置の状態では、径方向への収縮力を発生させることなく、筒状部本体５０の径方向における外側に配置させることができる。このため、折り返し部６０は、筒状部本体５０を外側から容易に覆うことができ、筒状部本体５０の外側に容易に配置することができる。本実施形態１では、グロメット１は、製造工程におけるグロメット１の成形時に、折り返し部６０が筒状部本体５０側に折り返された装着位置の状態で成形される。 At that time, since the total length of the inner surface 61 in the circumferential direction is longer than the total length of the inner surface 51 of the tubular portion main body 50 in the circumferential direction, the folded-back portion 60 is mounted folded back toward the tubular portion main body 50. In the position state, the tubular portion main body 50 can be arranged outside in the radial direction without generating a contraction force in the radial direction. Therefore, the folded-back portion 60 can easily cover the tubular portion main body 50 from the outside, and can be easily arranged on the outside of the tubular portion main body 50. In the first embodiment, the grommet 1 is molded in a state where the folded portion 60 is folded back toward the tubular portion main body 50 at the time of molding the grommet 1 in the manufacturing process.

グロメット１に配索材Ｗを挿通する際には、このように折り返し部６０を折り返した装着位置の状態で挿通する。グロメット１に配索材Ｗを挿通する際には、挿通空間部４０の大きさを大きくすることのできる工具（図示省略）を挿通空間部４０に通し、挿通空間部４０における軸線方向Ｘに交差する所定の方向における大きさを大きくした状態で挿通する。その際に、グロメット１は、折り返し部６０を折り返すことにより、軸線方向Ｘにおける全長が短くなっているので、工具を通し易くなっており、当該工具によって、挿通空間部４０の所定の方向における大きさを容易に大きくすることができる。配索材Ｗは、グロメット１の挿通空間部４０の大きさを工具によって大きくした状態で、挿通空間部４０に挿通する。 When the wiring material W is inserted through the grommet 1, the folded-back portion 60 is inserted in the folded-back mounting position. When inserting the wiring material W into the grommet 1, a tool (not shown) capable of increasing the size of the insertion space 40 is passed through the insertion space 40 and intersects the axial direction X in the insertion space 40. Insert in a state where the size in a predetermined direction is increased. At that time, since the total length of the grommet 1 in the axial direction X is shortened by folding back the folded-back portion 60, it is easy to pass a tool through the grommet 1, and the size of the insertion space portion 40 in a predetermined direction is increased by the tool. Can be easily increased. The wiring material W is inserted into the insertion space 40 in a state where the size of the insertion space 40 of the grommet 1 is increased by a tool.

なお、本実施形態１のグロメット１は、実際には、上述したように各部が装着位置にある位置関係で一体成形されるので、成形された状態で、折り返し部６０が装着位置にある状態となっている。このため、本実施形態１のグロメット１は、上記のような折り返し作業を要せずとも、装着位置にある状態で、容易に配索材Ｗを挿通する作業を行うことができる。 In addition, since the grommet 1 of the present embodiment 1 is actually integrally molded in the positional relationship in which each part is in the mounting position as described above, the folded portion 60 is in the mounting position in the molded state. It has become. Therefore, the grommet 1 of the first embodiment can easily insert the wiring material W in the mounted position without requiring the folding operation as described above.

そして、配索材Ｗを、グロメット１の挿通空間部４０に挿通したら、筒状部本体５０の外側に折り返されている折り返し部６０を、段差部６２から軸線方向Ｘにおいて本体部１０が位置する側の反対側に位置する使用位置の状態に折り返す（図１、図２、図３参照）。これにより、グロメット１は、軸線方向Ｘにおける長さが長くなるため、配索材Ｗを、長い長さで覆うことができ、配索材Ｗのより広い範囲を、グロメット１で覆うことができる。折り返し部６０を、使用位置にした状態のグロメット１で配索材Ｗを覆ったら、筒状部２０と配索材Ｗとの外側から、粘着テープを連続して巻き付ける。これにより、筒状部２０と配索材Ｗとを一体化させる。 Then, when the wiring material W is inserted into the insertion space portion 40 of the grommet 1, the folded portion 60 folded back to the outside of the tubular portion main body 50 is positioned at the main body portion 10 in the axial direction X from the step portion 62. It folds back to the state of the used position located on the opposite side of the side (see FIGS. 1, 2, and 3). As a result, since the grommet 1 has a long length in the axial direction X, the wiring material W can be covered with a long length, and a wider range of the wiring material W can be covered with the grommet 1. .. When the folded portion 60 is covered with the grommet 1 in the used position, the adhesive tape is continuously wound from the outside of the tubular portion 20 and the wiring material W. As a result, the tubular portion 20 and the wiring material W are integrated.

以上で説明した実施形態１に係るグロメット１、ワイヤハーネスＷＨは、グロメット１の折り返し部６０が、本体部１０が位置する側の反対側に位置する使用位置の状態で使用される。このため、グロメット１やワイヤハーネスＷＨの使用時には、配索材Ｗが挿通される筒状部２０は、軸線方向Ｘにおける長さが長い状態で配索材Ｗを覆うことになる。これにより、グロメット１は、挿通空間部４０内により確実に水が浸入し難くすることができ、止水性能を高めることができる。 The grommet 1 and the wire harness WH according to the first embodiment described above are used in a state where the folded portion 60 of the grommet 1 is located on the opposite side to the side where the main body portion 10 is located. Therefore, when the grommet 1 or the wire harness WH is used, the tubular portion 20 through which the wiring material W is inserted covers the wiring material W with a long length in the axial direction X. As a result, the grommet 1 can more reliably prevent water from entering the insertion space 40, and can improve the water stopping performance.

また、配索材Ｗにグロメット１を装着する際には、折り返し部６０を折り返した装着位置の状態にし、軸線方向Ｘにおける筒状部２０の長さが短い状態で装着するため、容易に装着することができる。これにより、グロメット１の装着時における作業性を向上させることができる。これらの結果、グロメット１の組み付け作業時の作業性の低下を抑制しつつ、止水性能を向上させることができる。 Further, when the grommet 1 is attached to the wiring material W, the folded portion 60 is placed in the folded mounting position, and the tubular portion 20 in the axial direction X is mounted in a short length, so that the grommet 1 can be easily mounted. can do. This makes it possible to improve workability when the grommet 1 is attached. As a result, it is possible to improve the water stopping performance while suppressing a decrease in workability during the assembly work of the grommet 1.

また、折り返し部６０は、使用位置において、内面６１の周方向における全長が、筒状部本体５０の内面５１の周方向における全長よりも長くなっている。これにより、折り返し部６０は、筒状部本体５０側に折り返された状態では、径方向への収縮力を発生させることなく筒状部本体５０の径方向における外側に位置させることができる。従って、折り返し部６０を装着位置にして筒状部２０の内側に配索材Ｗを挿通させる際に、より確実に容易に挿通させることができる。この結果、グロメット１の組み付け作業時の作業性をより確実に向上させることができる。 Further, in the used position, the total length of the folded-back portion 60 in the circumferential direction of the inner surface 61 is longer than the total length of the inner surface 51 of the tubular portion main body 50 in the circumferential direction. As a result, the folded-back portion 60 can be positioned on the outer side in the radial direction of the tubular portion main body 50 without generating a contraction force in the radial direction in the state of being folded back toward the tubular portion main body 50. Therefore, when the wiring material W is inserted inside the tubular portion 20 with the folded-back portion 60 in the mounting position, it can be inserted more reliably and easily. As a result, the workability at the time of assembling the grommet 1 can be improved more reliably.

また、折り返し部６０は、使用位置において、内面６１の直径が筒状部本体５０の内面５１の直径より大きく、筒状部本体５０との間に段差部６２を有するため、折り返し部６０の内面６１の周方向における全長を、より確実に筒状部本体５０の内面５１の周方向における全長よりも長くすることができる。これにより、折り返し部６０を、筒状部本体５０側に折り返した装着位置の状態において、より確実に径方向への収縮力を発生させることなく、筒状部本体５０の径方向における外側に折り返し部６０を位置させることができる。この結果、グロメット１の組み付け作業時の作業性をより確実に向上させることができる。 Further, since the diameter of the inner surface 61 of the folded-back portion 60 is larger than the diameter of the inner surface 51 of the tubular portion main body 50 and has a stepped portion 62 between the folded-back portion 60 and the tubular portion main body 50, the inner surface of the folded-back portion 60 is formed. The total length of 61 in the circumferential direction can be more reliably made longer than the total length of the inner surface 51 of the tubular portion main body 50 in the circumferential direction. As a result, in the state where the folded portion 60 is folded back toward the tubular portion main body 50 side, the folded portion 60 is folded outward in the radial direction of the tubular portion main body 50 without generating a contraction force in the radial direction more reliably. The unit 60 can be positioned. As a result, the workability at the time of assembling the grommet 1 can be improved more reliably.

なお、グロメット１は、段差部６２の肉厚を筒状部本体５０、折り返し部６０の肉厚よりも薄くなるように形成されてもよい。この場合、グロメット１は、段差部６２が筒状部本体５０と折り返し部６０とを折り返し可能に接続するヒンジ部として機能し、筒状部本体５０と折り返し部６０との折り返し作業をやり易くすることができる。 The grommet 1 may be formed so that the wall thickness of the step portion 62 is thinner than the wall thickness of the tubular portion main body 50 and the folded portion 60. In this case, the grommet 1 functions as a hinge portion in which the step portion 62 folds and connects the tubular portion main body 50 and the folded portion 60, facilitating the folding work between the tubular portion main body 50 and the folded portion 60. be able to.

［実施形態２］
実施形態２に係るグロメット１は、実施形態１に係るグロメット１と略同様の構成であるが、折り返し部６０が折り畳み部６５を有する点に特徴がある。他の構成は実施形態１と同様なので、その説明を省略すると共に、同一の符号を付す。 [Embodiment 2]
The grommet 1 according to the second embodiment has substantially the same configuration as the grommet 1 according to the first embodiment, but is characterized in that the folded portion 60 has a folded portion 65. Since the other configurations are the same as those in the first embodiment, the description thereof will be omitted and the same reference numerals will be given.

図６は、実施形態２に係るグロメット１の斜視図であり、図７は、図６に示すグロメット１の断面図である。実施形態２に係るグロメット１は、実施形態１に係るグロメット１と同様に、本体部１０と筒状部２０とを有しており、筒状部２０は、筒状部本体５０と折り返し部６０とを有している。このうち、折り返し部６０は、装着位置において周方向に開き、使用位置において周方向に折り畳まれる折り畳み部６５を有している。 FIG. 6 is a perspective view of the grommet 1 according to the second embodiment, and FIG. 7 is a cross-sectional view of the grommet 1 shown in FIG. The grommet 1 according to the second embodiment has a main body portion 10 and a tubular portion 20 as in the grommet 1 according to the first embodiment, and the tubular portion 20 has a tubular portion main body 50 and a folded portion 60. And have. Of these, the folded-back portion 60 has a folded portion 65 that opens in the circumferential direction at the mounting position and is folded in the circumferential direction at the used position.

詳しくは、実施形態２では、使用位置における折り返し部６０の内面６１の直径は、筒状部本体５０の内面５１の直径とほぼ同じ大きさになっている。折り畳み部６５は、このように形成される折り返し部６０において、使用位置の折り返し部６０を軸線方向Ｘに見た際に折り返し部６０を構成する壁部が、中心軸線Ｃを中心とする径方向における外側に突出して周方向に折り畳まれる形状で形成されている。使用位置の折り返し部６０において径方向に突出する折り畳み部６５は、軸線方向Ｘにおいて折り返し部６０が形成される範囲に亘って形成されている。換言すると、折り畳み部６５は、軸線方向Ｘに延びる中空のリブ状に形成されている。本実施形態２では、折り畳み部６５は、折り返し部６０の４箇所に形成されており、４箇所の折り畳み部６５は、中心軸線Ｃを中心とする周方向において等間隔で配置されている。 Specifically, in the second embodiment, the diameter of the inner surface 61 of the folded-back portion 60 at the use position is substantially the same as the diameter of the inner surface 51 of the tubular portion main body 50. In the folded portion 65 formed in this way, when the folded portion 60 at the used position is viewed in the axial direction X, the wall portion constituting the folded portion 60 is in the radial direction centered on the central axis C. It is formed in a shape that protrudes outward and is folded in the circumferential direction. The folded portion 65 that protrudes in the radial direction at the folded portion 60 at the use position is formed over the range in which the folded portion 60 is formed in the axial direction X. In other words, the folded portion 65 is formed in the shape of a hollow rib extending in the axial direction X. In the second embodiment, the folded portions 65 are formed at four positions of the folded portion 60, and the four folded portions 65 are arranged at equal intervals in the circumferential direction about the central axis C.

折り返し部６０は、使用位置における内面６１の直径が、筒状部本体５０の内面５１の直径とほぼ同じ大きさになっているが、このように折り畳み部６５を有しているため、使用位置における内面６１の周方向における全長は、折り畳み部６５の分、長くなっている。つまり、折り畳み部６５は、中心軸線Ｃを中心とする径方向における外側に突出しているため、折り畳み部６５の内面６１も含めた折り返し部６０の内面６１の周方向における全長は、折り畳み部６５が設けられていない場合における折り返し部６０の内面６１の周方向長さと比較して長くなっている。このため、使用位置における折り返し部６０の内面６１の周方向における全長は、筒状部本体５０の内面５１の周方向における全長よりも長くなっている。 The diameter of the inner surface 61 of the folded-back portion 60 at the use position is substantially the same as the diameter of the inner surface 51 of the tubular portion main body 50, but since the folded portion 60 has the folded portion 65 in this way, the use position The total length of the inner surface 61 in the circumferential direction is longer by the amount of the folded portion 65. That is, since the folded portion 65 protrudes outward in the radial direction centered on the central axis C, the total length of the folded portion 60 including the inner surface 61 of the folded portion 65 in the circumferential direction is calculated by the folded portion 65. It is longer than the circumferential length of the inner surface 61 of the folded-back portion 60 when it is not provided. Therefore, the total length of the inner surface 61 of the folded-back portion 60 at the use position in the circumferential direction is longer than the total length of the inner surface 51 of the tubular portion main body 50 in the circumferential direction.

なお、折り畳み部６５の数や、中心軸線Ｃを中心とする径方向における高さは、折り返し部６０を装着位置にした際における内面６１の直径や、折り返し部６０を形成する壁部の厚さ等に基づいて設定するのが好ましい。また、折り畳み部６５の軸線方向Ｘにおける長さは、筒状部２０のうち、折り返し部６０として設定する部分の軸線方向Ｘにおける長さに基づいて設定するのが好ましい。 The number of folded portions 65 and the height in the radial direction about the central axis C are the diameter of the inner surface 61 when the folded portion 60 is mounted and the thickness of the wall portion forming the folded portion 60. It is preferable to set based on the above. Further, the length of the folded portion 65 in the axial direction X is preferably set based on the length of the portion of the tubular portion 20 set as the folded portion 60 in the axial direction X.

実施形態２においても、グロメット１に配索材Ｗを挿通する際には、折り返し部６０を折り返した状態で挿通する。図８は、図６に示すグロメット１の折り返し部６０を折り返した状態の斜視図である。図９は、図８に示すグロメット１の断面図である。折り返し部６０を折り返す際には、折り畳み部６５における本体部１０寄りの端部付近の位置から、筒状部本体５０が位置する側に向けて折り返す。これにより、折り返し部６０は、内面６１が外表面になる状態で、中心軸線Ｃを中心とする径方向における筒状部本体５０の外側に折り返され、装着位置に位置する状態になる。その際に、折り返し部６０に形成される折り畳み部６５は、装着位置においては、中心軸線Ｃを中心とする周方向に開いた状態になる。つまり、折り畳み部６５は、折り返し部６０が使用位置の状態では、中心軸線Ｃを中心とする周方向に折り畳まれる形状で形成されているが、折り返し部６０が装着位置の状態では、折り畳まれていた折り畳み部６５が、中心軸線Ｃを中心とする周方向に開いた状態になる。これにより、折り返し部６０は、装着位置の状態では、中心軸線Ｃを中心とする周方向に大きな張力が発生することなく、筒状部本体５０の径方向における外側に位置することが可能になる。 Also in the second embodiment, when the wiring material W is inserted through the grommet 1, the folded-back portion 60 is inserted in a folded state. FIG. 8 is a perspective view of the folded portion 60 of the grommet 1 shown in FIG. 6 in a folded state. FIG. 9 is a cross-sectional view of the grommet 1 shown in FIG. When folding back the folded-back portion 60, the folded-back portion 60 is folded back from a position near the end of the folded portion 65 near the main body portion 10 toward the side where the tubular portion main body 50 is located. As a result, the folded-back portion 60 is folded back to the outside of the tubular portion main body 50 in the radial direction centered on the central axis C with the inner surface 61 being the outer surface, and is positioned at the mounting position. At that time, the folded portion 65 formed in the folded portion 60 is in a state of being opened in the circumferential direction about the central axis C at the mounting position. That is, the folded portion 65 is formed in a shape that is folded in the circumferential direction about the central axis C when the folded portion 60 is in the used position, but is folded when the folded portion 60 is in the mounted position. The folded portion 65 is in a state of being opened in the circumferential direction about the central axis C. As a result, the folded-back portion 60 can be positioned outside in the radial direction of the tubular portion main body 50 without generating a large tension in the circumferential direction about the central axis C in the mounted position. ..

折り返し部６０は、装着位置の状態においても、中心軸線Ｃを中心とする周方向の大きな張力が発生しないため、径方向への収縮力を発生させることなく、筒状部本体５０の径方向における外側に位置することが可能になっている。このため、折り返し部６０は、筒状部本体５０を径方向における外側から容易に覆うことができ、筒状部本体５０の外側に容易に配置することができる。本実施形態２では、実施形態１とは異なり、グロメット１は、製造工程におけるグロメット１の成形時に、折り返し部６０が使用位置の状態で成形されるが、折り返し部６０に折り畳み部６５が形成されることにより、大きな収縮力を発生させることなく、装着位置に折り返すことができる。 Since the folded-back portion 60 does not generate a large tension in the circumferential direction about the central axis C even in the mounted position, it does not generate a contraction force in the radial direction and is in the radial direction of the tubular portion main body 50. It is possible to be located on the outside. Therefore, the folded-back portion 60 can easily cover the tubular portion main body 50 from the outside in the radial direction, and can be easily arranged on the outside of the tubular portion main body 50. In the second embodiment, unlike the first embodiment, the grommet 1 is molded with the folded portion 60 in the used position when the grommet 1 is molded in the manufacturing process, but the folded portion 65 is formed on the folded portion 60. As a result, it can be folded back to the mounting position without generating a large contraction force.

グロメット１に配索材Ｗを挿通する際には、このように折り返し部６０を装着位置に折り返した状態で挿通するため、グロメット１の軸線方向Ｘにおける全長が短くなっている状態で挿通することができる。これにより、グロメット１に配索材Ｗを挿通する際に使用する工具を挿通空間部４０に通し易くなっており、当該工具によって、挿通空間部４０の所定の方向における大きさを容易に大きくすることができる。配索材Ｗは、グロメット１の挿通空間部４０の大きさを工具によって大きくした状態で、挿通空間部４０に挿通する。 When inserting the wiring material W into the grommet 1, since the folded portion 60 is inserted in the state of being folded back to the mounting position in this way, the grommet 1 is inserted in a state where the total length in the axial direction X is short. Can be done. As a result, the tool used for inserting the wiring material W into the grommet 1 can be easily passed through the insertion space 40, and the tool can easily increase the size of the insertion space 40 in a predetermined direction. be able to. The wiring material W is inserted into the insertion space 40 in a state where the size of the insertion space 40 of the grommet 1 is increased by a tool.

配索材Ｗを、グロメット１の挿通空間部４０に挿通したら、装着位置に折り返されている折り返し部６０を使用位置の状態にする（図６、図７参照）。これにより、グロメット１は、軸線方向Ｘにおける長さが長くなるため、配索材Ｗを、長い長さで覆うことができ、配索材Ｗのより広い範囲を、グロメット１で覆うことができる。折り返し部６０を、使用位置にした状態のグロメット１で配索材Ｗを覆ったら、筒状部２０と配索材Ｗとの外側から、粘着テープを連続して巻き付ける。これにより、筒状部２０と配索材Ｗとを一体化させる。 After the wiring material W is inserted into the insertion space 40 of the grommet 1, the folded portion 60 folded back to the mounting position is brought into the state of the used position (see FIGS. 6 and 7). As a result, since the grommet 1 has a long length in the axial direction X, the wiring material W can be covered with a long length, and a wider range of the wiring material W can be covered with the grommet 1. .. When the folded portion 60 is covered with the grommet 1 in the used position, the adhesive tape is continuously wound from the outside of the tubular portion 20 and the wiring material W. As a result, the tubular portion 20 and the wiring material W are integrated.

以上で説明した実施形態２に係るグロメット１、ワイヤハーネスＷＨは、折り返し部６０は、装着位置において周方向に開き、使用位置において周方向に折り畳まれる折り畳み部６５を有しているため、折り返し部６０の内面６１の周方向における全長を、より確実に筒状部本体５０の内面５１の周方向における全長よりも長くすることができる。これにより、折り返し部６０を、筒状部本体５０側に折り返した装着位置の状態において、より確実に径方向への収縮力を発生させることなく、筒状部本体５０の径方向における外側に折り返し部６０を位置させることができる。この結果、より確実にグロメット１の組み付け作業時の作業性の低下を抑制しつつ、止水性能を向上させることができる。 In the grommet 1 and the wire harness WH according to the second embodiment described above, the folded portion 60 has a folded portion 65 that opens in the circumferential direction at the mounting position and is folded in the circumferential direction at the used position. The total length of the inner surface 61 of the 60 in the circumferential direction can be more reliably made longer than the total length of the inner surface 51 of the tubular portion main body 50 in the circumferential direction. As a result, in the state where the folded portion 60 is folded back toward the tubular portion main body 50 side, the folded portion 60 is folded outward in the radial direction of the tubular portion main body 50 without generating a contraction force in the radial direction more reliably. The unit 60 can be positioned. As a result, it is possible to improve the water stopping performance while more reliably suppressing the deterioration of workability during the assembling work of the grommet 1.

また、折り返し部６０に折り畳み部６５を形成することによって、折り返し部６０の内面６１の周方向における全長を、筒状部本体５０の内面５１の周方向における全長よりも長くするため、折り返し部６０の外径が大きくなることを抑制することができる。これにより、配索材Ｗを挿通した後の筒状部２０の外径を小さくすることができ、配索材Ｗを挿通したグロメット１のコンパクト化を図ることができる。 Further, by forming the folded portion 65 in the folded portion 60, the total length of the inner surface 61 of the folded portion 60 in the circumferential direction is made longer than the total length of the inner surface 51 of the tubular portion main body 50 in the circumferential direction. It is possible to suppress an increase in the outer diameter of the. As a result, the outer diameter of the tubular portion 20 after the wiring material W is inserted can be reduced, and the grommet 1 through which the wiring material W is inserted can be made compact.

また、参考例として、チューブやブーツ等の配索材Ｗを覆う部材に、実施形態１、２に係るグロメット１における筒状部２０のような筒状部本体５０と折り返し部６０とを有する構成を適用してもよい。 Further, as a reference example, the member covering the wiring material W such as a tube or boot has a tubular portion main body 50 such as the tubular portion 20 in the grommet 1 according to the first and second embodiments and a folded portion 60. May be applied.
